Schools start at 7:30 for High School kids causing them to wake up between 5:30 and 6:30 for school. Teenagers have an internal clock that makes it hard for them to go to bed before 11 o'clock and have their minds ready to work at 8. They need atleast 9 1/4 hours of sleep. Most kids are lucky to get 6 or 7. School start times should be pushed back so kids minds can be ready to learn.
